What does the name Sinai mean? The Talmudic interpretation is
surprising — and somewhat shocking:

“What is Mount Sinai? The mountain that brought enmity
(sin'ah) upon the nations of the world.” (Shabbat 89b)

What is the nature of this animosity? What does it have to do with
Mount Sinai?

Why Sinai?

Where would one expect that God would reveal His Torah to the
Jewish people? The logical place would be on the holiest mountain
in the world — Jerusalem’s Mount Moriah, the site of the Binding of Isaac,
Jacob’s holy “gate to heaven” (Gen 28:17), the spot where both
Temples stood. Why did the revelation of the Torah take place
outside of the Land of Israel, in the middle of the desert?

The fact that the Torah was not given to the Jewish people in their
own land, but rather in a desert, in no-man’s land, is very
significant. This indicates that the inner content of the Torah is
relevant to all peoples. If receiving the Torah required the
special holiness of the Jewish people, then the Torah should have
been given in a place that reflects this holiness. Revelation on
Mount Sinai attests to the Torah’s universal nature.

This idea is corroborated by the Talmudic tradition that “God
offered the Torah to every nation and every tongue, but none
accepted it, until He came to Israel, who received it” (Avodah Zarah
2b). This Midrash is well known, but it contains an implication
that is often overlooked. How could God offer the nations something
that is beyond their spiritual level? It is only because the Torah
is relevant to all peoples that their refusal to accept it reflects
so harshly on them.

The Torah’s revelation on Mount Sinai, as a neutral location
belonging to none and thus belonging to all, emphasizes the
disappointment and estrangement from God that the nations brought
upon themselves by rejecting the Torah and its ethical teachings.
It is for this reason Mount Sinai “brought enmity
upon the nations of the world.”

In the future, however, the nations will recognize this mistake and correct it:

“In those days, it shall come to pass that ten men
from all the languages of the nations will take hold
of every Jew by a corner of his cloak and say, ‘Let
us go with you, for we have heard that God is with
you.'” (Zachariah 8:23)
